Title: The impact of the degree of competition in IT industry on operating performance during financial crisis
Authors: Lee, Sangho; Nam, Changi; Lee, Hongkyu
Abstract: This study examines whether competition improves corporate performance in Korean economy. Market competition promotes managerial efforts for cost reduction and innovation, while market concentration enables managers to enjoy a "quiet life". The effect of competition can be substituted, to some extent, by that of financial distress. Financial constraint also puts managers in more efforts for higher efficiency of firm. Our analysis of the 2001-2009 panel data of 1,800 Korean firms supports the hypothesis of positive relationship between competition and performance. The negative effect of financial distress is also more evident in highly concentrated markets such as IT industry.2011-01-01T00:00:00ZImplications of communication multiplexity for digital inequality: The role of online social networking skillshttp://hdl.handle.net/10419/52324

Title: The broadband debate: A documentary research on the broadband policy in Australia
Authors: Li, Grace
Abstract: Against a current trend of investing in the next generation networks (NGNs) by using public funds, the Australian government has recently initiated a so-called National Broadband Networks (NBN) project to invest up to AUD$36 billion tax payer's money on building a national wide fibre broadband network aiming to cover 93 per cent Australian by 2020. As being the most costly infrastructure-building project in Australian history, the NBN project will use a public-private-partnership as the instrument to deliver super-fast broadband services, create jobs and promote the country's economy at large. This article will critically analyse the NBN project in Australia and highlight the challenges that are coming alone at this early stage of the deployment, so the Australia's experience of pubic investment in broadband networks can be shared and lessons can be learned.2011-01-01T00:00:00ZInvestment, dynamic consistency and the sectoral regulator's obectivehttp://hdl.handle.net/10419/52341
Title: Investment, dynamic consistency and the sectoral regulator's obective
Authors: Brito, Duarte; Pereira, Pedro; Vareda, João
Abstract: We explore the separation of powers between the legislative and the executive branch of government as a way of overcoming the dynamic consistency problem of regulatory policy towards investment. We model the industry as a regulated duopoly. The incumbent is a vertically integrated firm that owns a wholesaler and a retailer. The entrant owns a retailer. Either retailer needs access to the input produced by the wholesaler to operate. The incumbent can make an investment that improves the quality of the input produced by the wholesaler. The regulator sets the access price and is unable to commit. The legislator sets the regulator's objective function and is able to commit. We derive general conditions under which having the legislator distort the regulator's objective function away from social welfare allows increasing the range of parameter values for which it is possible to induce socially desirable investment.2011-01-01T00:00:00Z
